The plates have Figure 22-68 Problem 84. length L = 10.0 cm and separation d = 2.00 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity vo of the electron makes an angle e = 45.0° with the lower plate and has a magnitude of 6.00 x 10° m/s. (a) Will the electron strike one of the plates? (b) If so, which plate and how far horizon- tally from the left edge will the electron strike? 7. 1:0
